描述
### Is this a regression?
- [ ] Yes, this behavior used to work in the previous version

P.S. A bit similar problem was there: https://github.com/angular/components/issues/28557
### Reproduction
StackBlitz link: https://stackblitz.com/edit/stackblitz-starters-xvgkha?file=src%2Findex.html,src%2Fmain.ts
Steps to reproduce:
1. Click **"Ron"** option (it becomes true)
2. Type in `input` letter **"J"**
3. Remove letter **"J"**
4. See that option **"Ron"** is false.
5. Type in input letter **"R"** or click outside `input`
6. See that option **"Ron"** is true.
### Expected Behavior
Option should be rendered immediately based on its internal state (`isSelected()/isActive()`).
### Actual Behavior
Option requires one more event to be rendered based on its internal state (`isSelected()/isActive()`).
### Environment
- Angular: 17
- CDK/Material: 17.3.3
- Browser(s): Chrome and Safari
- Operating System (e.g. Windows, macOS, Ubuntu):

调研方向
从链接的 StackBlitz 复现开始,尤其查看 src/index.html 和 src/main.ts,并跟踪 CdkListbox 和 cdkOption 的筛选步骤。比较列表恢复到初始内容后所选选项的渲染状态。完成的标准是:选项能够根据其内部 isSelected()/isActive() 状态立即渲染,而不需要再次触发输入或焦点事件。
